(V36) SYNOPSIS ObtainBattSemaphore( ) void ObtainBattSemaphore( void ); FUNCTION Aquires exclusive access to the system nonvolatile ram. INPUTS RESULTS NOTES SEE ALSO BUGS battmem.resource/ReadBattMem battmem.resource/ReadBattMem NAME ReadBattMem -- Read a bitstring from nonvolatile ram. (V36) SYNOPSIS Error = ReadBattMem( Buffer, Offset, Len ) D0 A0 D0 D1 ULONG ReadBattMem( APTR, ULONG, ULONG ); FUNCTION Read a bitstring from nonvolatile ram. INPUTS Buffer Where to put the bitstring. Offset Bit offset of first bit to read. Len Length of bitstring to read. RESULTS Error Zero if no error. NOTES The battery-backed memory is checksummed. If a checksum error is detected, all bits in the battery-backed memory are silently set to zero. Bits in the battery-backed memory that do not exist are read as zero. Partial byte reads (less than 8 bits) result in the bits read being put in the low-order bits of the destination byte. SEE ALSO BUGS battmem.resource/ReleaseBattSemaphore battmem.resource/ReleaseBattSemaphore NAME ReleaseBattSemaphore -- Allow nonvolatile ram to others. (V36) SYNOPSIS ReleaseBattSemaphore( ) void ReleaseBattSemaphore( void ); FUNCTION Relinquish exclusive access to the system nonvolatile ram. INPUTS RESULTS NOTES SEE ALSO BUGS battmem.resource/WriteBattMem battmem.resource/WriteBattMem NAME WriteBattMem -- Write a bitstring to nonvolatile ram. (V36) SYNOPSIS Error = WriteBattMem( Buffer, Offset, Len ) D0 A0 D0 D1 ULONG WriteBattMem( APTR, ULONG, ULONG ); FUNCTION Write a bitstring to the nonvolatile ram. INPUTS Buffer Where to get the bitstring. Offset Bit offset of first bit to write. Len Length of bitstring to write. RESULTS Error Zero if no error. NOTES The battery-backed memory is checksummed. If a checksum error is detected, all bits in the battery-backed memory are silently set to zero. Partial byte writes (less than 8 bits) result in the bits written being read from the low-order bits of the source byte. SEE ALSO BUGS
